Application filed February 6,..1911. Serial No. 606,726.

To all whom it may concern Be it known that I, CARL SATTLER, engineer, a subject of the King of Prussia, and

residing at Stubenrauch-Platz 3, Steglitz, Berlin, Germany, have. invented new and useful Improvements in Machines for Nailing Uppers to Soles, of which the following is a specification.

This invention-relates to a machine for nailing uppers to such soles which bear nailing, preferably to wooden soles, and consists in feeding before each blow of the hammera nail below the hammer to be driven through the upper which is tightly drawn over alast into the wood by one blow of the thereof. Fig. 3 the upper developed. Fig.

'4 a front view of the machine. Fig. 5 is a side view of the machine and section through the driving mechanism of the hammer. Fig.

6 is aplan thereof. Fig. :7 shows on an enlarged scale a front view of the nail-feeding device and a section at the place wherethe nails enter. Fig. 8 is a vertical section through the storing channel at the place where the nails enter. Fig. 9 is a side-view of Fig. 7. Figs. 10 and 11 show respectively aside view and a plan of the nailreceiver in front of the storing channel. Fig. 12 shows the device'for preliminary nailing the shoe. Fig. 13 shows the parts of the deviceshown in Fig. 12 in another position. Fig. 14 shows the same device as Fig. 12 with parts in yet another position. Fig. 15 is a plan of Fig. 14. "Figs. 16 and 17 are respectively a side view and a front view of the cam disk for actuating the hammer and the nail receiver.

14 and 15, to which the upper 6 is to be nailed. In order to prevent the nailheads from projecting from the surface of t the wood sole, a groove c-- is cut all around into the same below its top edge, into the inner edge dof which the nails are driven in the direction shown, after the upper has been drawn tight over the last.

In the upper part 1 Figs. l, 5 and 6 of the frame 2 is mounted a shaft 3 upon whichis keyed a pulley 4 which has motion imparted by'the belt 5 and the pulley 6 on the driving shaft. This drive may be uncoupled by means of the hand-lever 7, Fig. 5. ,Upon the shaft 3 is also employed the friction-clutch 8, 9, the cone 8 of which is loose and slidable and can be brought in engagement with the cone 9 by means of the lever 10, 11, rod 12 and pedal 13. At the end of the shaft 3 is secured the cam disk 14, Figs. 5, 16 and 17, upon thepcriphery of which rests the roller 15 of the hammerhead 16 placed under the influence of the springs 17, 18 in tension, Fig. 1. The hammer-head is longitudinally guided in the upper partof the casing 19 surrounding the cam-disk 14; by means of the rod 20 and in the lower part 21 by means of the, hammer 22. The lower end of the hammer guide tapers ofi' toa point and serves for the reception and the transmission. of the nails one of which will always pass through the side-channel 23 and enter into the space 24' below the hammer 22 before each blow.

The nails are positioned behind each other, Figs. 10 and ll. in a channel 27 formed by two rails and 26, the mouth of .the said channel being closed during each ceiver 28 mounted in the bearing 32 with a.

lever 33, the free end of which is; connected with a rod. guided in the projection 34;, 35 6f the cam-casing 19 and having attached a roller 36. This roller is under the influence of the spring 37 and raised by a cam 38 cast in one with theeam 14.

The nails are fed into the channel 27 I the drum 40 secured upon the shaft 39, Figs. 4, G, 7 and 9, filled with nails and slowly rotated by means'of the intermediate drive 43, 44, 45 and 46. The rope pulley 4G is situ- 5 ated adjacent to the nail drum 40. On the side opposite to the rope pulley 46 project through the side 47 of the drum 40 the inclined rails 25 :"nd 26, and at this point the. drum 40 has round plate covering the drum opening 49 and having at itse-xit an aperture 50 for the nail heads. 51, and} 53 arranged on the interior of the drum serve to raise the nails, to slip otl as the wings arrive opposite to the channe] 2? and fall against a battle-plate 76, Fig.

8, from which they are conveyed to and cause to drop in the direction of thechannel 27. There being always a considerable number of nails in the drum atleast one nail'will always fall into the position suitable for entering the ehanne1'27 and form with'those following a, continuous row or supply. In order that nails'which -may come to lie across the channel 27 willjn ot interfere'with the formation of the row of nails, a spring-catch, 54, Fig. Q, 'is'secured to the side of the drum 40, the free end. of which glides over the top edge of (the rails, and 26 and strips off the nails-restingon the top immediatelyin fIOIli'r, of the exit opening. In order to permit ofcharging the drum 40 with nails, its periphery is provid'ed with an opening which can be closed by a lid 55.

vice for clamping the upper b--' over the last efor the purpose of bringing the upper around the last. The said device con? sists of two grippers 56 and 57, 58, Figs; 13,

4C double-armed. lever on the stud 59 and-the free end of which has a set-screw 60 hearing against the curved part of an abutment piece 61 which is rigidly connected with the sole rest 62 and is under the influence of a spring 63. A. second abutment-piece 65 is provided having a handle (34: by means of which the abutment-piece 61 can also be displaced by hand against the pressure of the spring 63, All theseparts are arranged along the rest '62 guided in the bracket 67. The bracket 67 has twopirots 68 and 69 which engage in eyes 70 and 71 carried by the neck 72 ot' the machine-stand. The down-move- 55 ment of the bracket 67 can be limited by the set-screw 74:. on the ring 73 is arrangeda The wings Below ythe hammer 22 is situated the de- 14 and 15, the upper one 57, 58 forming a,

U machine. turns the: rest 75"beloiv the hammer, places the edge of the upperinto' the 75 groove on, the heel of the sole and then depressing the pedal 13 brings by means of the leverandrod 10, 11 and 12 the coupling into engagement which causes the shaft 3 with its cam 14 to rotate. The hammer 22 8Q beingraise'd by the cam 14:, the springs"17' 'and 18' will be compressed and when the roller 15 leaves the cam 14, are released and cause the hammer to strike. The blow f; the hammer drives.the-nail=belownvith one 35 blow into the sole, the workman holding the work fast withboth hands. Owing to-the. stronglycurved surface of the rest, 5,. ;the workman has sufficient freed0m of motion to insure of bringingpthe imil-gro'ove below. the hammer. The workman then drives a, secondv nail in about one centimeteraway from: the first one, afterwhich ,he brings. H the coupling out-of engagemen,t-. r The upper is then raised,- the last placed in and the toc." of the work brought forward, itbeing esscir, .tial to hold the up er securely against the edgein order thatit will conform with the last. For this purpose the workman turns the rest 62. with .the drawing-over device below the hammer, pIacesthejedge lot the upper into-the open mouth of the gripper and presses the sole-against. themest. During this movement the. abutment passes the -lever arm 58 upward, so that the gripper month; closes..- This pressure ismaintained and-the sole on the rest is broughtfrom the position ofiFig. l3 into the position of Fig. until- I the inneredge of the groove coincides 'with the path ofthe hammer and approximately halves the inclined side of the groove In this position of the,sole, in which-the upper is drawn over or in front the'heel to the toe for-the purpose. of causing theupper to lay a well against. the last, theworkman brings the coupling 8, 9. in engagement again to drive-in a nail. Afterward, the workman relieves the pressure against the rest, so that the upper is freed and thereby the gripper becomes free to clamp (say about e e asmeter fartheraway) another part of the upper, and secure, the same by drivingjna nail Eor this purpose the. workman draws theuppenas previously, tighnbi-ings the groove again into the path oft'he hammer so that the second nail can be driven in. In

the same manner he drives a few nails in at. each side. The upper having thus been so cured .to thesol'e at, the principal places (heel, toeand sides) the w'orkrr zni moves the work along the rest from the heel to the toe (or vice versa) in the meantime exert- -1ng pressure thereon and with each blow of the hammer drives in a nail at distances of about one centimeter. lVhencontinuing the nailing the use of the grippers is discontinned, the upper being secured at four points having been drawn sufficiently tight over the last and already brought into form. If the Workman has had some practice he need not bring the coupling again out of engagement to continue 'the nailing which otherwise would'be essential, as between the first and, second blow of the hammer, due to the oscillation of the nail-receiver 28, a nail has already been brought out of-the nail-channel through the guide-groove 23 below the hammer 22. The oscillation of the nail-receiver and the distance at which its two prongs are situated from each other is so'calculated that when one of the prongs has liberated the front nail, its passage is freed and the other prong holds back the bulk of the nails in the channel.

When. placing the sole against the rest and the introducing edge of the upper into the mouth of the gripper, owing to the pres sure of the Work upon the sole rest, the gripper cannot at once close sufliciently to hold it securely to be drawn over the last. For this reason the handle (34 is provided, which when-turned in the direction of the arrow mc W- the abutment at the beginning forward against the abutment-piece 61 and thereby draws with it the rest against which the wori. bears. After the upper is held securely the sole can thenbe further pressed against the rest. until the groove is brought again in the path of the hammer.
